Roon nucleus & Lumin T2

Good evening ladies and gentlemen,

I'm a new Roon nucleus owner and have paired that with a Lumin T2. Reasons for adding Roon are mainly for a better operating system (lumin ap is horrible & crashes often), and to have one system to rule all my devices etc etc.

I found pairing the Roon to the Lumin a little confusing. What I control on the roon AP (select to play) will not appear on the Lumin screen. I've also read that one should shut off the up sampling in the T2 AP, but I can't find anything in the Lumin ap that mentions up sampling?

Any help tips and tricks are very welcomed.
